Integrating KWL Plus Technique with Mind Mapping to Develop Reading Comprehension Skills of Thai 9 Graders

The purposes of the study were 1) to examine the effectiveness of the KWL plus mind mapping learning management on Thai grade 9 students’ reading comprehension and 2) to study the participants’ satisfaction with the KWL plus mind mapping learning management. The study employed a one-group experimental design, with 25 students from a public school in Mahasarakham province participating. The research instruments included a KWL Plus mind mapping learning management plan, a reading comprehension test, and a satisfaction questionnaire. Data were collected through pre-tests, post-tests, and during the implementation of six sub-learning lessons. The effectiveness of the learning management plan was assessed using process-product effectiveness (E1/E2), post-test effectiveness (E2), and an effectiveness index (E.I.). The results indicated significant improvements in students' reading comprehension, with the learning management plan showing a high effectiveness index (E.I. = 0.82). Additionally, the students expressed a very high level of satisfaction (average x̄ = 4.85) with the learning approach. This study contributes to the field of reading development by providing evidence of the combined effectiveness of KWL and mind mapping techniques in enhancing language learning in similar educational contexts.
